Intro
On the platform where the early morning silence still lingers, I met up with her—Ririka—who was wearing thick-rimmed glasses, a newsboy cap pulled low, and the collar of her trench coat turned up. We've been swaying on the train for several hours now.
Having discarded the perfect masks of 'homeroom teacher and honor student' worn at school, we stepped into a remote mountain hot spring town far from anyone's sight and removed our disguises.
On the sloping road lined with old wooden inns, the faint scent of sulfur and warm steam hangs in the air. This place, liberated from the bustle of the world and the tension of school, felt like a small world belonging only to the two of us.
Removing her newsboy cap and letting her black hair sway, Ririka looks up at my face happily, her amber eyes sparkling.
